Application November 21, 1936, serial No. 112,171 In Germany February 28, 1936 3 Claims.

The present invention relates to shirt collars, and methods of making the same, and particularly to stiff or reinforced but flexible collars, especially such collars made of paper or the like including those having a coating of varnish or lacquer of the type of. cellulose ester. Y

When rolling or rounding such collars it often happens that small creases, cracks or breaks occur in the outer surface of the collar which ruin the appearance of the collar and make it unsightly.

It is therefore the'object of the present invention to avoid such irregularities in the outer surface of a collar and to produce a collar with a plain and unmarred surface.

Another object residesin producingl a collar of paper or like material having the appearance of linen or similar fabric so that the paper collar is indistinguishable from a normal shirt collar.

Another object consists in provi-ding a collar at the inside thereof with one or more groove-like impressions, which may extend parallel with the upper edge of the collar or at an angle thereto.

'I'hese and other obj ects are disclosed in the following detailed description and shown in the drawing, in which:

Fig. 1 is a diagrammatic sketch of. a part of an apparatus for producing a collar according to the invention, While Figs. 2 and 3 `disclose collars with horizontal or 30 vertical grooves, respectively, produced according to the new process and by means of an apparatus as shown for example in Fig. 1.

In rolling, rounding or bending of collars, particularly collars made of paper, cardboard or like material, and especially such collars which are provided with a layer of cellulose 'ester and a coating of varnish or similar material thereon, the outer surfaces have a great tendency to tear or crease because of insuiiibient flexibility of the material. It is therefore easily noticeable that such a collar is not made of linen or similar material but of a cheap material, regardless of the quality of the paper used.

These disadvantages are overcome by the present invention. The collar 2 is first cut out from the blank in the desired shape and folded to form a turned-over collar. It is then provided at the inner fold 4 closely adjacent the upper edge 6 with a narrow impression. As shown in Fig. 2, this 50 impression may consist of one or more grooves 8 extending parallel with the upper edge of the collar, or it may consist of a plurality of short vertical grooves I0 as shown in Fig. 3, or of similar grooves but extending at an angle of less than 90 to the upper edge.

By means of these impressions a collar is obtained which can be rolled together as much as desired.

which, in turn, is driven by any conventional type v of motor (not shown). In Fig. 1 roller I2 is shown as provided with short vertical ridges 20. Of course, a roller with one or more horizontal ridges or a roller with inclined ridges may be substituted for roller I2 if the collar is to be provided with horizontal or diagonal grooves. Roller I2 including ridges 2E) preferably consists of a non-oxidizing material, such as porcelain or the like, to prevent soiling of. the collar.

Roller I4, likewise journalled in support I6, has a relatively smooth outer surface and may consist of a similar material to that of roller I2. Depending on the type of material used for the collar, roller I4 may also be of steel, or of a resilient material such as rubber or the like.

In the operation of the device, the collar 2, after being out out from the blank to the correct size and shape and then folded, is inserted between rollers I2 and I4 With the inside 22 toward roller I2. The ridges 20 will press into the material and cause the collar to bend slightly and gradually around roller I 2. They will likewise compound the material to some extent and strengthen the collar near its upper edge 24. Roller I 4 may either be driven by the same .gear mechanism as roller I2 and at the same speed of rotation, or it may be rotated through the friction communicated to its outer surface by roller I2 and collar 2.

It is obvious that the grooves may be impressed by various types of devices and, therefore, I do not want to be limited to the specific type of apparatus shown.

I claim:

1. A shirt collar comprising an outer fold and an inner fold, said inner fold having at least one substantially continuous narrow groove-like irnpressicn therein extending substantially parallel with the upper edge of the collar and located below such upper edge, said impression being located Wholly within the upper part of the inner fold.

2. In a collar as claimed in claim 1, said impression comprising a continuous groove extending longitudinally of the collar.

3. In a collar as claimed in claim 1, said impression comprising closely spaced grooves extending in a series substantially parallel with and adjacent the upper edge of the collar, said grooves being inclined relative to said edge.
